Subject: [PATCH] Check configured addresses again if previous check found none
 of them

Currently, aria2 checks configured addresses at the startup. But there
are chances that interfaces are not setup at that moment. For example,
if aria2 is used as daemon, it may start before network interfaces
up. To workaround this, we check addresses again if both addresses are
not configured at the startup.
